Which statements best describe the steps geologists follow to compare rock layers at distant locations? Select three options.

Find the absolute age of rocks at both locations.
Give a relative age to a layer at one location.
Compare a layer at one location to layers at other locations.
Identify index fossils in one or more layers at one location.
Collect fossils from different locations to study the organisms’ lifestyles.

Give a relative age to a layer at one location. Compare a layer at one location to layers at other locations. Identify index fossils in one or more layers at one location.

Explanation:

Geologists use the descriptive term correlation to match and compare rock layers at various distant locations. Through this, they can regionally match rock layers from place to place and establish the chronostratigraphic sequence over a place.

The relative age of a layer at one location is very indicative of the order of the formation of the rock relative to other rock types. This can help us understand if two rock types in different places are synchronous.Lithological correlation is very important in comparing rocks that falls between different terrains. Index fossils are important and they help to ensure that exact rocks are classified using their specific time signatures. These fossils have very short stratigraphic range and they lived for a short period in time.
